Definition
BBP Timeout: The 1 mS baseband
processing timer has failed
self-test.
RS 232 Receiver Failure: The GPS
Receiver did not receive any
initialization data from the host
computer on the RS 232 port.
EEPROM Failure: The EEPROM
memory has failed its checksum.
RS 232 Channel 2 Failure: The
second RS 232 UART on the
receiver has failed the loop-back
test. This self-test can only be
enabled during test mode on the
receiver and should not be seen in
normal operation.
BBP Underflow: The baseband
processing loop detected an error
in the 1mS processing loop.
BBP Overflow: The baseband
processing loop detected an error
in the 1mS processing loop.

Suggested Action
It could be one of the following, in the order of
probability:
1. The 5 volt supply to the antenna could be
shorted out in the coax. This disables the oscillator
in the GPS.
2. The flex cable between the Receiver and Main
Board may have come out of the socket in the GPS.
3. Bad TCXO or ASIC on receiver module in GPS.
Substitute the GPS unit.
It could be one of the following, in the order of
probability:
1. The flex cable between the Receiver and Main
Board may have come out of the socket in the GPS.
2. Bad 32KHz crystal, UART, or processor on
Receiver Module in GPS. Substitute the GPS unit.
Bad EEPROM. Return for service.
It could be one of the following, in the order of
probability:
1. The receiver was put in test mode without
looping back the two serial ports.
2. Bad ASIC or Microprocessor on the receiver.
It could be one of the following, in the order of
probability:
1. The flex cable between the Receiver Board and
the Main Board mat have come out of the socket in
the GPS.
2. Bad TCXO, MMIC, or ASIC on the Receiver
Board.
It could be one of the following, in the order of
probability
1. The flex cable between the Receiver Board and
the Main Board mat have come out of the socket in
the GPS.
2. Bad TCXO, MMIC, or ASIC on the Receiver
Board.
